Excuses and rationalizations for slutty behavior, often heard from girls who have slept with 17+ guys (including threesomes with guys they just met that night). Lower back tattoos are absolutely a dead give-away.

Girl: "I'm not a slut; I have daddy issues!"
Dude: "That slut logic doesn't work on me, bitch."

Girl: "I got this tramp stamp before I knew what they were called."
Dude: "That's some solid slut logic, right there."

Girl" "It's the only way I can connect with people!"
Dude: "Justify however you want with your slut logic. You're still a filthy tramp."
